373 Indicator 4 3 13

  1. 1. “ If you can’t stand the heat…” By Dave Sandrick 2/8/10
  2. 2. Science Standard 3 – The Physical Setting <ul><li>Indicator 4.3.13 – Observe and describe the things that give off heat, such as people, animals, and the sun. </li></ul><ul><li>Taken from http://dc.doe.in.gov/Standards/AcademicStandards/StandardSearch.aspx </li></ul><ul><li>Link to activity: </li></ul>
  3. 3. Definitions <ul><li>Observe – To be or become aware of, especially through careful and directed attention; notice. </li></ul><ul><ul><li>Observing is the fundamental science process skill. We observe objects and events using all our five senses, and this is how we learn about the world around us (from http://www.longwood.edu/cleanva/images/sec6.processskills.pdf ) </li></ul></ul><ul><li>Describe – To give an account of in speech or writing. </li></ul><ul><li>Heat – a form of energy characterized by random motion at the molecular level </li></ul><ul><li>Molecular - Of, relating to, or consisting of molecules (the smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces). </li></ul><ul><li>Taken from: www.thefreedictionary.com </li></ul>
  4. 4. Background information <ul><li>HEAT </li></ul><ul><li>When molecules of any kind of atoms get more energy in them than they had before, they move faster, and we call that &quot;heat&quot;. When the molecules move faster, they hit against each other and bounce apart, and so they end up further apart from each other than they were before. The energy can come from sunshine , or from volcanoes , or from friction , or nuclear fusion , or many other sources. </li></ul><ul><li>Things are hot if their molecules are moving quickly, and cold if their molecules are moving more slowly. Temperature is a way of measuring how fast the molecules are moving. </li></ul><ul><li>http://www.historyforkids.org/scienceforkids/chemistry/atoms/heat.htm </li></ul>
  5. 5. List as many things that you can think of that give off heat. Draw a picture in the box to go with one item from your list. <ul><li>Things that give off heat </li></ul><ul><li>Picture </li></ul>Note: The BOLDFACED words from this slide forward are from various Bloom's Taxonomy categories.
  6. 6. If you had to CLASSIFY your things into three (3) groups, how would you do it?
  7. 7. Making heat – Part 1 This activity connects with indicator 4.2.3: Make simple and safe electrical connections with various plugs, sockets, and terminals. <ul><li>In the box, you will find a baggie labeled “D BATTERY” which will have a D battery, 2 strips of aluminum foil, and one small light. See if you can make the light work. Record your attempts (by drawing a picture) in your science journal. Once you are able to make the light work, decide whether or not the light gives off any heat. (After three attempts, look at the picture at the back of this handout.) </li></ul>
  8. 8. Making heat – Part 1 <ul><li>_________________________________________________________________________________________________________________________________________________________________________________________________________________ </li></ul>
  9. 9. Making heat – Part 2 This activity connects with indicator 4.3.11: Investigate, observe, and explain that things that give off light often also give off heat. <ul><li>Also in the box is a baggie labeled “6V BATTERY.” This baggie contains everything you need to light the bulb included in the baggie. Once you are able to make the bulb light, decide whether or not THAT light bulb generates any heat. Compare the two light bulbs. Why do you think one bulb gave off more heat than the other? Write your thoughts on the next slide. </li></ul>
  10. 10. Making heat – Part 2 <ul><li>_____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ </li></ul>
  11. 11. Making heat – Part 3 This activity connects with indicator 4.3.12: Investigate, observe, and explain that heat is produced when one object rubs against another, such as one’s hands rubbing together. <ul><li>Rub your hand together for 30 seconds. What happened to your hands? Explain what is happening based on what you have learned so far about heat. </li></ul><ul><li>_________________________________________________________________________________________________________________________________________________________________________________________ </li></ul>
  12. 12. Assessment <ul><li>1.) Have you ever been burned by something that gave off heat?  DESCRIBE your experience by writing it on the lines below. </li></ul><ul><li>_________________________________________________________________________________________________________________________________________________________________________________________________________________________________ </li></ul><ul><li>2.) EXPLAIN how the heat was produced (by the object that burned you). </li></ul><ul><li>____________________________________________________________________________________________________________________________________________________________________________________ </li></ul>

  14. 14. “… get out of the kitchen.” <ul><li>“ If you can’t stand the heat, get out of the kitchen.” </li></ul><ul><li>The quote is from President Harry S. Truman. What do you think he meant by that statement? </li></ul><ul><li>_______________________________________________________________________________________________________________ </li></ul><ul><li>That kind of statement is called an IDIOM. </li></ul>
